Improvement in hose-couplings



UNITE STATES ANDREW J. MORSE, OF BOSTON, MASSACHUSETTS.

lMPROVEMENT IN HOSE-COUPLINGS.

Specification forming part of Letters Patent No. Et'2A7ill, dated January 18, 1876; application filed December 21, 1875.

To all whom it may concern:

Be it known that 1, ANDREW J. MORSE, of Boston, Suffolk county, Massachusetts, have invented an Improvement in HoseGouplings, of which the following is a specification:

This invention relates to hose-couplings, the object being to cap or cover the hose end, and hold it firmly between rings fitted within and outside the hose, and made to compress and hold the hose end, by compressing the outer ring against it, or by expanding the inner ring. The upper ends of the rings are provided with flanges, and the outer end ofthe hose-cappin g rings is compressed by the action of an inclinedfaced binding-ring that forcesinward and compresses the substance of the ring, as the hinding-ring is attached to the coupling-section.

The drawing shows a section of one end of a coupling provided with the improvement.

The couplin g-sectionais provided with screwthreads I), to receive the usual loose-running section, not shown, and at its opposite end it has the screw-threaded projection c, to which is attached the binding-ring cl, provided at its inner upper portion wit-h screw-threads to fit the screw-threads in projection c, and below the shoulderf of the binding-ring'that meets the end of c, the interior piece of the binding ring is inclined, as at e, becomingsmaller to ward the lower end of the binding-ring. The inner capping and holding ring g, has, at its upper end, a flange, h, and at its lower end an annular projection, or series of projections, z'. The outer capping-rill g j has, at its upper end, an inWardly-projecting llange adapted to extend over and form a bearing for the flanged portion of g, the flange ot'the outer ringj restin g against a shoulder on the inner portion of the coupling-section. The hose 7c is suitably lined with rubber, or it may be of rubber or fibrous material, or of other usual hose-fabric.

When this hose is to be coupled, the bindingring is passed over the end, then the inner ring g is inserted within the hose, the flange h preferably meeting the hose end, and then the outer ring j is passed over the outer portion of the end of the hose and its contained inner ring. In this position the hose-end is confined between the outer and inner faces of the two cylindrical rings, and the lower end of j terminates,

preferably, a little above the annular projection 2'. The coupling-section is now applied,its screw-threaded portion a is connected with the upper screw-threaded portion of the bindingring, and the binding-ring, as it is drawn longitudinally over the hose and outer riugj, (the upper end of the latter ring resting against the shoulder on the coupling-section,) compresses the lower end of the outer ring j from the position shown in dotted lines to the position shown in full lines, the lower end of the outer ring closing in upon the hose moreor less according to the degree of inclination of e or its length, and the end of j meets the upper portion of the annular projection, substantially as shown. A space is left between the upper portions of the rings 9 to receive the portion of the hose crowded from the nipped or compressed portion toward the end of the hose.

This invention is an improvement on Patent No. 166,130, heretofore granted to me, and is specially adapted to hold rubber-lined or rubber or fibrous hose, and it will be noticed that the capping-portions gj, in this application of my invention, are immovably fixed by contraction of a ring, and it will be noticed, also, that the capping parts, as in that patent, have no screw-threads, nor do they rotate when being attached to the hose, so as to disconnect the rubber lining from the fibrous material or to cut the hose, and, in this invention, the couplingsection may be removed from the hose for repairs, and yet leave the end of the hose capped.

The binding-ring may be provided with spanner projections, as shown on the coupling-section.

The inner cappingring might be expanded and the outer ring might be somewhat tapered so as to grasp the hose end, and the rings so fitted might be placed between the binding-ring and coupling-section, constructed as described, but, in such case, the outer capping-rill g would be shaped before applying the binding-ring, as it is now shown as shaped by the action of the binding-ring.
